Summary
The ADAS dataset has a total of 1,167 observations. The company with the most ADAS crashes is Tesla with 875 crashes. The model with the most ADAS crashes is the Tesla Model 3. For the ADS dataset, it has a total of 436 observations. The company with the most ADS crashes is Jaguar with 875 crashes. The model with the most ADS crashes is the Jaguar I-Pace with 186 crashes.

Table 2: ADS vehicle crashes by roadway surface type
These tables were included because roadway surface has a big impact on the way cars drive, so it is important to evaluate how ai cars handle certain roadway surfaces. These tables show that the dry roadway surface has the most ADAS and ADS vehicle crashes. So, the roadway surface type does not affect the performance of the ai vehicles. This means that the cause of the crash must be something else like the roadway type or brand of car.
Charts 1: ADAS / ADS Crashes Per Location in the United States
Figure 1: Distribution of where ADAS car crashes have happened around the United States.
Figure 2: Distribution of where ADS car crashes have happened around the United States.
The purpose of these maps are to observe where and how many crashes are happening in locations around the United States. Most crashes seem to happen in California based on the large and dark red circles found there (particularly in Los Angeles), but also in Texas and New York. The results might be linked to higher populations and manufacturers in these states. Hover over the points on the map to get information on the city and total number of crashes there.
Chart 2: Types of Car Crashes in ADAS vs ADS
Figure 3: Pie chart show the proportions of
differing crash types for ADAS vehicles.
Figure 4: Pie chart show the proportions of
differing crash types for ADS vehicles.
The pie chart illustrates what types of car crashes are most prevalent in ADAS and ADS in the United States. Most cases in ADAS are with fixed objects and vehicles whereas the top 3 in ADS are passenger cars, SUVs, and pickup trucks. This makes sense since most of these vehicles are driven on busy roads where other vehicles are common.
Chart 3: Number of ADAS / ADS Crashes Per Roadway Type
Figure 5: Bar graph showing the amount of roadway types that ADAS vehicles were driving on when a crash occurred.
Figure 6: Bar graph showing the amount of roadway types that ADS vehicles were driving on when a crash occurred.
These bar graphs depict which roadway types are most prevalent in the crashes of ADAS and ADS in the United States. It is seen that the most crashes for ADAS happens on the highway, while it is on the intersection for ADS. The ADAS roadway types might be the result that drivers like to turn on ADAS most likely when they are on highways. For ADS, it might mean that these cars struggle to identify red lights.
